I think Wilhoit’s law[1] is also a major factor: these guys appear to have taken things like codes of conduct as a personal affront because in many cases it was the first time penalties started being applied to people they identified with as fellow in-group members. You can see this in lots of cases - e.g. compare SV elite reactions to the alleged shoplifting epidemic to the way the same people feel about cheating on taxes or misleading investors for orders of magnitude more money.
